Recounts one of the most controversial moments in the Old Testament—when Abraham was commanded by God to sacrifice his son Isaac on the mountain of Moriah.

His Only Son is a dramatic retelling of the biblical story of Abraham and Isaac from Genesis 22. The film focuses on God's command to Abraham to sacrifice his only son, Isaac, on Mount Moriah. It follows Abraham and his son as they travel to the mountain, while also incorporating flashbacks that provide insight into Abraham's life leading up to this pivotal moment.

The movie explores Abraham's struggle with carrying out the divine command and delves into the philosophical and psychological implications of the story. With a strong Christian, Biblical worldview, His Only Son draws connections between Abraham's story and the sacrificial death and resurrection of Jesus Christ.
